DOI: 10.3724/SP.J.1037.2011.00458, PP. 56-62
Keywords: Ti-50.8Ni-0.3Cr合金,形状记忆合金,时效,显微组织,超弹性
Abstract:
利用TEM和拉伸实验研究了时效工艺对Ti-50.8Ni-0.3Cr(原子分数,%)形状记忆合金(SMA)显微组织和超弹性的影响.随时效时间($t_{\rmag}$)延长,300℃时效态Ti-50.8Ni-0.3CrSMA的Ti3Ni4析出相呈细小颗粒状,400℃时效态合金的析出相由颗粒状逐渐变为针状,500℃时效态合金的析出相由针状逐渐变为粗片状.时效温度对析出相形态的影响比tag显著.随tag延长,300和400℃时效态合金的抗拉强度(σb)先增大后趋于稳定,σb(500℃)先减小后趋于稳定,且σb(400℃)>σb(300℃)>σb(500℃).300和400℃时效态合金的超弹性优于500℃时效态合金.随tag延长,该合金的应力诱发马氏体相变临界应力逐渐减小,300℃时效态合金的超弹性能耗(ΔW)降低,400℃时效态合金的ΔW升高,500℃时效态合金的ΔW先升高后降低.
